In the earliest stage of growth, almost all of the plants which have a resting period, begin their growth entirely depending on the reserve substance. The size of a newly formed plant body depends on both the amount of the utilized reserve substance and the economic ratio, or the efficiency of conversion of the reserve substance to the active plant body. The effect of the amount of the reserve substance on the economic ratio was examined with potato tubers of different sizes, and it was found that the ratio remained approximately constant (0.4-0.5) independently of tuber size. Almost the same ratio was obtained in the growth of the rice seedling in the dark under a wide range of temperature (15-30℃). So far as the present and other available data are concerned, it may be said that the plants, of which the reserve substance is mainly composed of carbohydrate, give more or less the same economic ratio of 0.5,irrespective of the difference in the initial amount of reserve substance and temperature.
